IMPROVEMENT IN ROLLS FOR UTILIZINGl THE FAG-ENDS OF RAILROAD RAILS.

Specification forming part of Letters Patent N o. 124,116, dated February 27, 1872.

To all whom t may concern:

Be it known that I, HENRY GHIsIIoLM, of Cleveland, in the county of luyahoga and State of Ohio, have invented certain new and Improved Rolls for utilizing worn and crop ends and other parts of steel and iron railway T- rails; and I do hereby declare that the following is a full, clear, and complete description thereof, reference being had to the accompanying drawing making part of the same.

SPECIFICATION.

Figure l is a side view of the chilled cast rolls and housing, Fig. 2, top view 5 Fig. 3, end View.

Like letters of reference refer to like parts in the several views.

The nature of my improvement consists in the peculiar formation or construction of cast rolls for the purpose of utilizing the butts, fag ends, worn-out, or old steel railway rails.

It is well known among those skilled in the art to which this invention belongs that steel cannot be perfectly welded together without much expense in time and labor, and re quiring borax or other iiux in the operation. lt is also well known that it cannot be piled either alone or with iron or other steel, andunited by Welding, hammering, or rolling into a compact and homogeneous mass, without re sorting to the use of iiux, much skill and labor.

By piling, lapping, fagoting, or folding of steel pieces together and alone, subjecting the same to a welding heat and vthe action of compression by rolls or hammering, seams will occur throughout the entire mass when the surface of the pieces are in contact, which prevents the pile or fagot sought to be welded together from being intimately combined and having that homogeneous character, free from iiaws and seams, so essential and important to the products of this manufacture.

Various eXpedients have been resorted to for the purpose of utilizing the butts or fagends cut off steel railway rails during the process of their manufacture, but which are found to be too expensive or im practicable, when compared with the improvements herein described 5 and which, in part, consists in the peculiar construction and arrangement of chilled cast rolls for reducing the fag-ends or butts of steel rails rection by the usual means. It will be observed that a section of the rolls, at a, is so turned out as to be in form similar to an ordinary railway rail, and through which, between the rolls, is first passed the piece of steel rail. In making this pass, the piece or butt is reduced in size and extended in length in the same proportion. After having passed through the rolls at a, it is then entered between the rolls at b, which compresses the metal vertically. The next passes are then through between the rolls at c, and afterward at d, the object being to reduce the fagend or piece of steel to a bar or rod. This is attained by subjecting the metal, as it comes from the rolls at d, to a further compression and reduction by being again passed through between the rolls at c or j', as may be found expedient in the manipulation. In some cases it may be advisable to pass the piece, as it comes fromd, through between the rolls at f, so as to compress the steel vertically. After the butt or piece has passed through between the rolls at e or f it no longer partakes of the form of a rail, but assumes that of a steel bar, which is again reduced by compression in passing between the rolls at g, and afterward between the rolls at h.

By this operation the butt or steel rail is reduced, by the action of the rolls, to a steel bar or rod of any desired size, and of va perfectly homogeneous character, without the seams or iiaws consequent upon lapping, piling, or fagotin g.

t will be noted that the foot and head of the rail is rolled down, without lapping or folding, onto the neck Aor web of therail, or being compressed upon it. The head and foot are so compressed and rolled out by the rolls, hav ing such peculiar form or construction, that the rail or piece of steel, during the series of passes, is reduced from an irregular shape to that of a uniform bar or rod.

By this process the metal is worked or rolled out longitudinally on its flat side, and vertically; and, by the influence of the rolls, the head, foot, and neck are all worked out at the same time, but independently of each other, to the extent that the different members of the rail do not lap or fold into each other during the process of conversion to a bar or rod.

the most or as convenient as any system for r the purpose desired.

Claims.

1. The rolls A B, provided with the series or system of grooves, of the form or construction described and shown, and arranged in relation to each other substantially as and for the purpose set forth.

2. The rolls A B, having the series of irregu lar-shaped and graduated grooves, of the form or construction shown at a c d, operating conjointly as and for the purpose substantially described.
